Definitions

  • This invention relates to a rolling screen with a screen such as an insect net or a sunshade cloth stored within a screen case.
  • the screen is wound on a take-up shaft rotatably held within the screen case. Accordingly, the screen can be automatically arranged extending over an opening of a building or the like while winding it out of the screen case. When the screen becomes no longer needed, it can be wound back into the screen case by taking it up on the take-up shaft.
  • Conventional rolling screens include those having a screen case arranged inside a window frame or the like.
  • the screen case is provided with a hollow take-up shaft rotatably arranged inside the screen case.
  • a screen such as an insect net or a sunshade cloth, is wound on the take-up shaft so that the screen is stored within the screen case.
  • the screen is wound out of the screen case so that it is automatically arranged extending over an opening of the window or the like.
  • the screen becomes no longer needed, it can be wound back into the screen case by taking it up on the take-up shaft.
  • the take-up shaft may be flexed and deformed by pulling force applied via the screen upon winding out the screen and during its use, and the take-up shaft may hence produce noise and/or prevent smooth winding-out and arrangement of the screen
  • the screen case may not be adequately arranged within a small depth of a frame of an opening of a building, for example, within a small depth of inner casing of an opening of a door or window.
  • a rolling wire screen which is used to prevent entry of insects, is received in a window end stile of a double sliding sash, namely, in a construction where a window end stile is provided with a channel of a square U-section which is open on a window end side of the stile, a rolled screen is stored in the channel, and a sliding glass sash is horizontally pulled or opened to cause the screen to extend over the opening
  • the depth of a window end stile of the double sliding sash is usually as small as 20 to 25 mm or so.
  • the outer diameter of the take-up shaft of this rolling wire screen must be as small as 10 mm or so.
  • the take-up shaft cannot therefore be provided with sufficient strength, possibly resulting in a substantial deformation due to flexion caused upon winding out the screen or during use of the screen. This deformation in turn results in waving of the screen, thereby making it impossible to fully achieve the object, that is, the prevention of entry of insects.
  • the take-up shaft tends to become more liable to arching before transmission of sufficient rotating force to the take-up shaft upon winding out the screen. It may hence become no longer possible to wind out the screen in some instances.
  • a wound-out portion of the net is generally left free at its upper and lower edges. Openings therefore tend to occur between the upper and lower edges of the net and the corresponding upper and lower frames of the opening of the building, leading to a problem that the wire screen cannot fully prevent insects from entering the building.
  • the upper and lower edges of the net are more susceptible to stretching and slacking than a central part of the net. This results in problems that the net may be stored in a folded state upon taking it up on a take-up shaft, and the net yarns are prone to loosening at the upper and lower edges, leading to breakage of the net.
  • reinforcing tapes such as of aluminum foils are generally sewn on and along opposite vertical side edges of the net.
  • the net is therefore thicker at the vertical side edges than the remaining part thereof, whereby stepped portions are formed along the vertical side edges.
  • the reinforced vertical side edges are fitted in guide slits, specifically in lipped opposite vertical side guide rails of a square U-section, so that the reinforced vertical side edges are held slidably up and down in the corresponding lipped opposite vertical side guide rails.
  • the opposite vertical side edges of the net can therefore be maintained within the corresponding guide rails when the net is caused to extend in a vertical direction.
  • Friction is however developed between the reinforced opposite vertical side edges of the net and the corresponding guide rails when the net is caused to extend or is taken up. Due to this friction, greater operating force is required upon causing the net to extend or retract and especially, significant operating force is required upon causing the net to extend downwards. The above friction also causes sliding noise upon operating the net in a vertical direction. Further, when the net is exposed to external pressure and substantially large load is applied to the opposite vertical side edges of the net, the opposite vertical side edges of the net may slip out of the guide rails. If this happens, it is very difficult to repair the vertical rolling wire screen. Its repair must hence be done by a professional repairman. This is certainly very cumbersome for the user.
  • An object of the present invention is therefore to improve the above-described drawbacks of the conventional art, and specifically to reduce the dimensions of a screen case, in which a take-up shaft with a rolling screen wound thereon is accommodated, for providing the screen case with wider applicability and higher operability as a final product and also to fully maintain the screen taut for the prevention of entry of insects and the like during its use in an extended state.
  • a rolling screen comprising:
  • a take-up shaft arranged rotatably about a central axis thereof within the screen case, said take-up shaft being normally biased in a screen-winding direction by a torsion spring, and
  • an outer peripheral surface of the screen wound on the take-up shaft is always maintained in contact with an inner wall of the screen case, said inner wall being located in a direction of winding-out of the screen, by pulling force applied to the screen upon extension of the screen or resilient force of a pressing spring when the screen is wound out or wound in.
  • the rolling screen according to this invention can be arranged between guide rails fixed on upper and lower frames of a sash.
  • the rolling screen can also be arranged between stiles of a sliding sash.
  • a rolling screen comprising:
  • a take-up shaft arranged rotatably about a central axis thereof within the screen case
  • the flexible net has been reinforced at a predetermined width in opposite side edge portions thereof, which extend at right angles relative to the take-up shaft, by coating the flexible net in the opposite side portions thereof with a liquid-form synthetic resin to form thin films and then hardening the thin films.
  • the opposite side edge portions of the flexible net can be improved in strength. It is therefore possible to prevent breakage of the flexible net and also to avoid slacking of the flexible net while the flexible net is used in an extended state.
  • a rolling screen comprising:
  • a take-up shaft arranged rotatably about a central axis thereof within the screen case
  • the flexible net when the screen case is caused to move in a direction along the guide rails, the flexible net is arranged extending over the opening without a slack by causing a wound-out portion of the flexible net to detachably engage the fasteners at opposite side edge portions of the flexible net and, when the screen case is caused to move in an opposite direction along the guide rails, the flexible net is wound into the screen case by taking up the flexible net on the take-up shaft while allowing the opposite side edge portions of the wound-out portion of the flexible net to disengage from the fasteners.
  • the flexible net can be supported by the guide rails via the engagement between the fasteners and the flexible net.
  • the flexible net can therefore be prevented from flaring at a central part of the flexible net, so that the flexible net can be used in an extended state without a slack.
  • a rolling screen comprising:
  • take-up shafts arranged rotatably within the screen cases, respectively, one of the take-up shafts carrying a sunshade screen wound thereon and the other one of the take-up shafts carrying a flexible net wound thereon, and
  • a selector arranged between the screen cases so that the screen cases can be selectively connected together or disconnected from each other;
  • one of the sunshade screen and the flexible net can be arranged extending over the opening as desired.
  • the two screen cases can be slidably arranged in an efficient fashion, thereby providing the rolling screen with very wide applicability as a final product.
  • Either the sunshade screen or the flexible net can be caused to extend over the opening of the building as needed.

  • the upright rolling screen according to the first embodiment of the present invention is designated at numeral 1.
  • This upright rolling screen 1 is installed within the depth of the interior wood casing 2 of the sash.
  • a flexible screen 5 such as an insect screen or sunshade cloth made, for example, of a polyester can be caused to extend by drawing the upright rolling screen 1 in a horizontal direction.
  • the screen 5 can be held in the extended state (see FIG. 2).
  • the screen 5 is fixedly joined at one end thereof with a take-up shaft 6--whose outer diameter is as small as half the diameter of a conventional take-up shaft, that is, about 10 mm or so--and at an opposite end thereof with an angle 4 which is brought into engagement with a movable upright member 3.
  • the screen 5 is wound on the take-up shaft 6 in such a way that the screen 5 can be paid out and taken up as desired.
  • a screen case 8 is formed in a channel shape so that the screen case 8, together with a case cover 7, can accommodate therein the take-up shaft 6 and the screen 5 wound thereon.
  • the take-up shaft 6 is supported rotatably about an axis 6' by shaft-supporting brackets 9 within the screen case 8.
  • the shaft-supporting brackets 9 are loosely fitted in guide grooves 11 of brackets 10 fixedly arranged on upper and lower edges of the screen case 8, respectively.
  • the take-up shaft 6 is arranged movably in the guide grooves 11 of the brackets 10 so that by resilient force of feedback springs 12 integrally secured on the shaft-supporting brackets 9 or by pulling force applied to the screen 5 upon its winding-out, an outer peripheral surface of the screen 5 wound on the take-up shaft 6 is always maintained in contact with support members 13 arranged at constant intervals on an inner wall of the screen case 8, said inner wall being located in a direction of winding-out of the screen 5.
  • the rolling screen 1 can be operated as will be described below.
  • the movable upright member 3 is horizontally drawn and the metal fitting is brought into engagement with the wood casing as shown in FIG. 2.
  • the take-up shaft 6 As the screen 5 wound on the take-up shaft 6 is paid out and the outer diameter of the take-up shaft 6 including the screen 5 wound thereon becomes smaller, the take-up shaft 6 progressively moves in a lower right direction as viewed in FIG. 2 while pulling the feedback springs 12 under progressively increasing force.
  • the outer peripheral surface of the screen 5 wound on the take-up shaft 6 can be always maintained in contact with the support members 13 arranged at constant intervals on the inner wall of the screen case 8, said inner wall being located in the direction of winding-out of the screen 5. Namely, as the screen 5 is paid out, the take-up shaft 6 is caused to move along the guide grooves 11 of the brackets 10 in the winding-out direction of the screen 5. Accordingly, the take-up shaft 6 rotates while the outer peripheral surface of the screen 5 wound on the take-up shaft 6 is always maintained in contact with the support members 13. As a consequence, even if the take-up shaft 6 begins to flex under pulling force applied thereto when the screen 5 is wound out, the pulling force applied on the take-up shaft 6 is borne by the support members 13.
  • the take-up shaft 6 is therefore protected from deformation which may otherwise occur by the pulling force. It is therefore no longer required to use, as the take-up shaft 6, a take-up shaft having an increased diameter in order to provide strength sufficient to prevent deformation of the take-up shaft 6 upon arrangement of the screen 5 in an extended state. This makes it possible to construct the screen case 8 itself compactly.
  • the extended screen 5 Upon storing back the extended screen 5 into the screen case 8, on the other hand, the fixed engagement of the movable upright member 3 is released. As a result, the extended screen 5 is taken up by the biasing force of the torsion spring (not shown) arranged on the take-up shaft 6 and is hence stored back into the screen case 8. As the extended screen 5 is wound back onto the take-up shaft 6, the outer diameter of the take-up shaft 6, including the screen 5 wound thereon, becomes greater. Owing to the arrangement of the feedback springs 12 attached to the take-up shaft 6, the take-up shaft 6 is always under pulling-back force which is applied toward an upper left side as viewed in FIG. 2.
  • the shaft-supporting brackets 9 with the take-up shaft 6 rotatably supported thereon are allowed to move back toward the upper left side as viewed in FIG. 2. Accordingly, the screen 5 is wound back onto the take-up shaft 6 while always being held between the take-up shaft 6 and the support members 13. This can eliminate such an inconvenience that the screen 5 may be wound back in a folded state.
  • the screen 5 Upon paying out the screen (5) from the take-up shaft 6 inside the screen case 8 or winding it back onto the take-up shaft 6, the screen 5 itself is always held between the take-up shaft 6 and entire surfaces of the support members 13 arranged at the constant intervals on the inner wall of the screen case 8. Friction is hence always developed between the screen 5 and the support members 13, leading to a potential problem that smooth rotation of the take-up shaft 6 may be hampered upon paying out or winding back the screen 5.
  • Production of the support members 13 with a low-friction material such as a synthetic resin results in smaller frictional resistance upon paying out and winding back the screen 5, so that smooth rotation of the take-up shaft 6 can be assured.
  • the support members 13 may be eliminated and instead, the screen 5 is supported in contact with an entire surface of an edge portion of the case cover 71 although the frictional resistance with the screen 5 somewhat increases.
  • FIG. 3 where the rolling screen 1 according to the first embodiment of the present invention is accommodated within the window end stile 15 of the sliding glass sash 14 in the double sliding sash.
  • the window end stile 15 with a pane fitted therein has an open channel pocket 17 on a side of a jamb 18, and a cover member 19 disposed in engagement with the jamb 18 is engageable with the window end stile 15 so that the open channel pocket 17 can be closed by the cover member 19.
  • the angle 4 to which the one end of the screen 5 is fixedly joined is secured on the cover member 19.
  • the take-up shaft 6 with the screen 5 wound thereon is accommodated within the open channel pocket 17 of the window end stile 15.
  • This take-up shaft 6 is rotatably supported on the brackets 9, which are loosely fitted in the guide grooves 11 of the brackets 10 fixed on the upper and lower ends of the window end stile 15, respectively.
  • the take-up shaft 6 is movable by pulling force applied upon arrangement of the screen 5 in an extended state and the resilience of the feedback springs 12 attached to the take-up shaft 6.
  • a support member 20 made of a synthetic resin and having a T shape in cross-section is inserted at a basal end thereof in a holding groove 17' formed in an inner wall of the open channel pocket 17 of the window end stile 15, whereby an outer peripheral surface of the screen 5 wound on the take-up shaft 6 is always maintained in contact with the support member 20.
  • the outer peripheral surface of the screen 5 wound on the take-up shaft 6 is supported by the entire surface of the support member 20 even when the outer diameter of the take-up shaft 6, including the screen 5 wound thereon, is reduced as a result of drawing and opening of the window end stile 15 in a horizontal direction.
  • the take-up shaft 6 is therefore prevented from flexion. This assures smooth rotation of the take-up shaft 6 upon paying out or winding back the screen 5.
  • the depth of a sliding glass sash mounted on two rails in a double sliding sash is generally limited to 25 mm or so at the maximum.
  • the width of an opening of the sliding glass sash 14 ranges from 800 to 850 mm in general, and a door opening is considered to have a similar width.

  • the net thickness is preferably 0.3 mm or greater.
  • the outer diameter of the take-up shaft 6, including the screen 5 wound thereon is set at 22 mm and the extended width of the screen 5 is set at about 800 mm, there is no choice other than reducing the outer diameter of the take-up shaft 6 to a level as small as 11 mm.
  • this take-up shaft 6 is used in a length as great as the height of a door and is supported only at the opposite ends thereof, this outer diameter is too small to withstand bending deformation of the take-up shaft 6 through flexion even when a thick-wall stainless pipe is used.
  • the construction of the first embodiment according to the present invention makes it possible to prevent deformation of the take-up shaft 6 which would otherwise take place by pulling force applied upon arrangement of the screen 5 in an extended state.
